Version 4.0

• Added another property to CompositionRoot to specify installers as prefabs re #96
• Changed global composition root to be a prefab instead of assembling together a bunch of ScriptableObject assets re #98
• Changed to lookup Zenject Auto Binding components by default, without the need for AutoBindInstaller. Also added new properties such as CompositionRoot, identifier, and made Component a list. Also works now when put underneath GameObjectCompositionRoot's.
• Added ability to pass in multiple types to the Bind() method. This opens up a lot of possibilities including convention-based binding. This also deprecated the use of BindAllInterfacesToSingle in favour of just BindAllInterfaces<>
• Added "WithArguments" bind method, to allow passing arguments directly to the type instead of always using WhenInjectedInto
• Added concept of EditorWindowCompositionRoot to make it easier to use Zenject with editor plugins
• Added "InheritInSubContainers" bind method, to allow having bindings automatically forwarded to sub containers
• Removed the different Exception classes in favour of just one (ZenjectException)
• Added 'AsCached' method as an alternative to 'AsSingle' and 'AsTransient'. AsCached will function like AsTransient except it will only create the object once and thereafter return that value
• Changed some methods that previously used 'params' to explicitly take a list, to avoid common errors
• Cleaned up InjectContext to be easier to work with
• Made significant change to how Factories work. Now there is just one definitive Factory class, and you can change how that factory constructs the object in your installers
• Changed the fluent interface to specify whether the binding is single or transient as a separate method, to avoid the explosion of ToSinglePrefab, ToTransientPrefab, etc. (now it's just ToPrefab)
• Renamed GlobalCompositionRoot to ProjectCompositionRoot and FacadeCompositionRoot to GameObjectCompositionRoot.
• Added more intuitive bindings for creating subcontainers. eg: Container.Bind().ToSubContainerResolve().ByPrefab()
• Added WithGameObjectName and WithGroupName bind methods to prefab or game object related bindings
• Made another big chagne to the fluent interface to avoid having duplicate methods for with Self and Concrete. Now you choose between Container.Bind().ToSelf() and Container.Bind().To(). ToSelf is assumed if unspecified
• Changed Triggers to directly expose the signal event so they can be used as if they are signals
• Added concept of ScriptableObjectInstaller - especially useful for use with settings
• Added ZenjectSceneLoader class to allow additively loading other scenes as children or siblings of existing scene
• Changed scene decorators to work more intuitively with the multi-scene editting features of Unity 5.3+. You can now drag in multiple scenes together, and as long as you use DecoratorCompositionRoot in scenes above a main scene, they will be loaded together.
• Removed IncludeInactive flag. Now always injects into inactive game objects. This was kinda necessary because validation needs to control the active flag
• Removed the concept of one single DependencyRoot in favour of having any number of them, using binding with identifier. Also added NonLazy() bind method to make this very easy
• Added new attribute ZenjectAllowDuringValidation for use with installer setting objects that you need during validation
• Changed validation to occur at runtime to be more robust and less hacky. Now works by adding dummy values to mark which dependencies have successfully been found
• Renamed BindPriority to BindExecutionOrder
• Removed support for binary version of Zenject. This was necessary since Zenject now needs to use some unity defines (eg. UNITY_EDITOR) which doesn't work in DLLs

Note that the documentation has not been updated yet to reflect all these changes.
